How It Works

Character Substitution

This tool replaces regular English characters with visually similar characters from other alphabets (primarily Cyrillic and Greek). These Unicode "lookalikes" appear identical to the original letters but are technically different characters.

Swap Percentage

Control what percentage of eligible characters get swapped. At 100%, all possible characters are replaced. At lower percentages, the tool randomly selects which characters to swap, creating more natural-looking text.

Zero-Width Spaces

When enabled, the tool inserts invisible Unicode zero-width space characters between letters. These characters are completely invisible but break up the text at a technical level, making it harder for automated systems to detect patterns.

Why Use This?

  • Bypass text filters and detection systems
  • Create unique-looking text for creative purposes
  • Test how systems handle Unicode characters
  • Make text stand out subtly

Example

Input: Hello World

Output: Ηеllo Wοrld

The 'H', 'e', and 'o' have been replaced with Greek/Cyrillic lookalikes
